Monolith: a monolithic pressure-viscosity-contact solver for strong two-way rigid-rigid rigid-fluid coupling

Abstract

Fig. 1. Our Monolith solver enables efficient and robust two-way simultaneous rigid-rigid and rigid-fluid coupling. (Left) Two hollow glass spheres containing inviscid liquid roll around within a basin as the liquid slides and splashes. (Middle) A boat carrying multiple loads is perturbed by ocean waves. (Right) When the glass spheres instead contain viscous liquid, the no-slip boundary condition, viscosity, and friction together bring the spheres more quickly to rest.
